Given numbers are 721,407,407,876

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 721,407,407,876 is 257059572.

Find LCM of 721,407,407,876 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

11 x 37 x 721 x 1 x 1 x 876 = 257059572

Therefore, the lowest common multiple of 721,407,407,876 is 257059572.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

721 x 407 x 407 x 876 = 104623245804

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

721 : 1, 7, 103, 721

407 : 1, 11, 37, 407

407 : 1, 11, 37, 407

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,407,407,876, is 1.

Now, the common factors can be found like this.

721:7x 103

407:11x 37

407:11x 37

876:2x 2x 3x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11x 37 = 407

Therefore, the value for common factors is 407.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 104623245804/(1x407)

LCM = 104623245804/407

LCM = 257059572

Thus, we can understand that the LCM of 721,407,407,876 is 257059572.
